Assessment requirements

Modification History

Release 2. Equivalent to MEA414 Remove light corrosion from aircraft with amended prerequisite codes.

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

  • applying WHS procedures relating to light corrosion removal, including the selection and correct use of PPE
  • recognising types of corrosion and of damage that exceeds light surface corrosion
  • applying enterprise procedures for removal of light corrosion
  • selection and use of applicable corrosion removal methods, equipment and tools
  • using MSDS
  • cleaning of surfaces following corrosion removal
  • correctly disposing of waste materials
  • cleaning and maintenance of equipment and tools.

The underlying skills inherent in this unit should be transferable across a range of tasks involving the removal of light corrosion damage from the surfaces of aircraft structure. It is essential that applicable processes, cleanliness requirements and safety precautions, including the correct use of PPE, and application of environmental protection procedures are fully observed, understood and complied with. Ability to interpret corrosion removal procedures and apply them in practice is critical.

This is to be demonstrated through corrosion removal using mechanical, manual and chemical means across a range of aircraft tasks.

Knowledge Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

  • relevant enterprise procedures and maintenance publications
  • WHS procedures relating to the removal of aerospace coatings, including PPE
  • how to obtain MSDS
  • types of chemicals used for corrosion removal and methods of application
  • mechanical methods that can be used for corrosion removal
  • cleaning methods following corrosion removal
  • environmental legislation and regulations relating to the storage, use and disposal of hazardous materials.

Assessment Conditions

  • Competency should be assessed in the workplace or simulated workplace using materials, tools and equipment specified in the maintenance manuals and applicable procedures. It is also expected that general and special-purpose tools and ground support equipment would be used where appropriate.
  • The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.
  • The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
  • A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on a representative range of light corrosion removal tasks using applicable mechanical, manual and chemical removal methods as listed in the Range of Conditions.
  • This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
  • Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
